AbstractBackgroundPhiladelphia chromosome negative myeloproliferative neoplasms (MPNs), including essential thrombocythemia, polycythemia vera, and myelofibrosis, have severe function‐limiting symptom burden that is experienced by the majority of patients. Previous studies have suggested that depression may be present in over a quarter of MPN patients, but to date no studies have evaluated the relationship between depression and other variables such as symptoms.MethodsA 70‐item internet based survey regarding fatigue and mood symptoms was developed by a multidisciplinary team of MPN investigators, patients and patient advocates including Patient Health Questionnaire and the Myeloproliferative Neoplasm Symptom Assessment Form was completed by over 1300 patients with MPN diagnosis.ResultsThere were 309 respondents (23%) with PHQ‐2 scores ≥ 3. In this analysis, we found worse systemic symptom burden in individuals reporting depressive symptoms.ConclusionThis analysis suggests the importance of depression in contributing to as well as confounding symptomatology in MPN patients, and suggests that this critical variable should also be addressed by clinicians and researchers alike when comprehensively assessing symptom burden etiologies.

Abstract Introduction Some Alzheimer's disease biomarker studies found amyloid changes 20 years or more in advance of expected symptoms, while cognitive changes lagged for more than a decade, but this apparent lag might reflect the sensitivities of the biomarker and cognitive assays used. How far in advance of incident amnestic mild cognitive impairment (MCI) does cognition begin to decline? Methods Longitudinal neuropsychological study of an apolipoprotein E e4 enriched cohort of cognitively normal individuals at entry. Linear mixed models for MCI converters (n = 65) and nonconverters (n = 719) fitted for each neuropsychological measure; annual changes compared between groups before and after linear model intersections (inflection points). Results 34 of 35 cognitive measures and 9 of 18 behavioral measures declined faster post‐inflection in the MCI converters; the earliest cognitive inflection point was nearly 20 years in advance of MCI diagnosis. Discussion The preclinical duration of cognitive and behavioral changes approaches the earliest reported biomarker changes.

Abstract Introduction: Myeloproliferative Neoplasm (MPN) patients encounter debilitating pain syndromes as a result of their disorder. Opioids are frequently employed in cancer-related pain but have been increasingly recognized for their risk profiles including accidental overdose, addiction and death. With many MPN patients facing near-normal life expectancies, chronicity of opioid use may increase the risk of adverse events. In this survey, we evaluated the prevalence of MPN opioid use, risk factors for negative outcomes and compared the features of this population to MPN patients not receiving opioid therapy. Methods: This study was performed by the MPN Quality of Life Study Group. A survey was designed by a team of MPN investigators experienced with MPN symptomatology. Patients completed the MPN-10, a 10 item survey of MPN symptoms completed on a 0 (absent) to 10 (worst imaginable) scale (Blood. 2011 Jul 14;118(2):401-8). Other surveyed tools included the Opioid Risk Tool (ORT) as well as DSMV criteria for Opioid Use Disorder (OUD). The survey was posted on high-traffic MPN-related webpages focused on patient education and advocacy (MPN Forum, MPN Net, MPN Research Foundation, MPN Voice)for a total of 28 days. Patients currently receiving opioids were compared to patients not receiving opioids and statistical significance was defined as p<0.05. Results Demographics A total of 416 patients completed the survey and were compared by active opioids use (n=69) vs. no active opioid use (n=347). Patients described a history of myelofibrosis (MF, 28.8%), polycythemia vera (PV, 44.2%) and essential thrombocythemia (ET, 26.9%). Most MPNs were diagnosed between 1-3 years ago (22.2%), 3-10 years ago (35.0%) or >10 years ago (30.4%). Patients were furthermore of expected mean age (60.7), primarily female (75.0%) and from the United States (66.6%). Few patients had a history of transformation to acute leukemia (0.5%), severe bleeding (12.3%) or blood clot (26.5%). Mean individual symptom scores and prevalences were 3.0 and 65.6% for abdominal discomfort and 3.3 and 59.4% for bone pain, respectively, indicating a low to moderate symptom burden. Patients Receiving Opioid Therapy Patients on opioid therapy (n=69) displayed a number of high risk features for adverse outcomes including a personal history of substance abuse (20.2%), respiratory disease (33%) and mental health disorders (60.1%). By DSMV criteria, 5.9% of opioid patients scored 'mild' and 2.9% scored 'moderate' for OUD (total 8.8%), consistent with prevalence in the general population. Approximately 24.6% of opioid-using patients scored moderate to high risk on the ORT but despite this, did not appear more likely to meet criteria for OUD (p=0.81). Palliative care and pain management were involved in only 34.3% of patients and side effects of opioids were discussed in only 70.1% of all cases. Opioid vs. Non-Opioid Patients Compared to patients not receiving opioid therapy, patients currently on opioid treatment were more likely to describe more frequent and/or more severe abdominal discomfort (88.4% vs. 61.0%, p<0.001; mean 5.0 vs. 2.6, p<0.001), bone pain (87.0% vs. 53.9%, p<0.001; mean 5.6 vs. 2.4, p<0.001), unintentional weight loss (41.2% vs. 21.4%, p=0.001), inactivity (94.2% vs. 71.5%, p<0.001), early satiety (84.1% vs. 58.2%, p<0.001), and impaired quality of life (mean 4.9 vs. 6.6, p<0.001). They were also more likely to describe regularly taking pain medications (85.5% vs. 34.5%, p<0.001) as well as attempt non-pharmacological treatments to manage symptoms (Figure 1). Despite more aggressive pain treatment approaches, only 42% of opioid patients reported satisfaction with their current pain plan vs. 62.2% of patients not receiving opioid therapy. Conclusions: MPN patients face significant symptom burden despite often limited reduction in life expectancy. Patients furthermore demonstrate a high prevalence of risk factors for opioid-related complications including overdose and substance misuse. Despite aggressive pain regimens, opioid patients are less likely to voice adequate symptom control or satisfaction with their pain treatment plans. Providers should be cognizant of opioid-related complications and consider subspecialty pain management referrals or adaptation of the JCO Clinical Practice Guidelines for Management of Chronic Pain in Survivors of Adult Cancers (J Clin Oncol. 2016 Sep 20;34(27):3325-45).

Abstract Introduction: MPN-related pain, including abdominal discomfort (53.2%), and bone pain (48.5%), is a prevalent complaint within the disorder and is associated with impaired patient quality of life, reduction in most functional domains and overall poor prognosis. Non-targeted treatments for MPN disorders have been previously shown to provide little symptomatic relief for MPN pain. To date, little is known about patient viewpoints on MPN pain, its relationship to other chronic pain syndromes and the impact of pharmacologic and non-pharmacologic pain therapies. In this study, we performed an international survey of MPN patients to better understand the prevalence and management of MPN pain. Methods: This study was performed by the MPN Quality of Life Study Group. A survey was designed by a team of MPN investigators experienced with MPN symptomatology. Survey content included the Barriers Questionnaire II (BQII), a 27-item survey validated to assess patient belief barriers to optimal management of cancer pain measured on a 0 (do not agree at all) to 5 (agree very much) scale (Pain. 2002 Oct;99(3):385-96.). Patients also completed the MPN-10, a 10-item survey of MPN symptoms completed on a 0 (absent) to 10 (worst imaginable) scale (Blood. 2011 Jul 14;118(2):401-8). The survey was posted on high-traffic MPN-related webpages focused on patient education and advocacy (MPN Forum, MPN Net, MPN Research Foundation, MPN Voice) for a total of 28 days. Survey questions evaluated patient demographics, pain histories, current and prior treatment strategies, as well as satisfaction with and barriers to available treatment options. Results: Demographics A total of 502 MPN patients (MF 26.9%, PV 44.2%, ET 28.9%) completed the survey. Patients were of expected mean age (60.5 years) and primarily female (74.9%). Most were from the United States (66.7%) and primarily English speaking (92.2%). Patients described being diagnosed with their MPN 3 to 10 years (35.4%) or >10 years ago (30.8%). Splenic enlargement was vocalized by 36.5% of patients and few patients had had a known history of blood clots (25.4%), severe bleeding (13.3%), conversion to acute leukemia (0.4%) or prior bone marrow transplant (1.4%). Patients described a treatment history of a variety of MPN therapies including aspirin (82.7%), hydroxyurea (60.6%), phlebotomy (40.6%), ruxolitinib (25.9%), interferon (18.5%), anagrelide (17.3%), active clinical trial (5.0%) and radiation treatment (0.4%). Pain Severity, Prevalence and Treatments Among surveyed patients, the MPN-10 mean was 28.3. Mean individual symptom scores and prevalence were 3.1 and 65.6% for abdominal discomfort and 3.0 and 60.4% for bone pain, respectively indicating a low to moderate symptom burden. Most patients had no prior history of chronic pain prior to their MPN diagnosis (47.1%), with chronic abdominal pain and chronic bone/muscle pain noted prior to MPN development in 5.6% and 20.8% of patients, respectively. Most patients felt that their chronic pain has either stayed the same (26.2%), worsened (28.3%) or significantly worsened (14.5%) since their MPN diagnosis. Many patients found pharmacologic and non-pharmacological therapies efficacious for individual pain symptoms, and 42.1% described regularly taking medication to control their pain (Table 1). Barriers to Pain Management Overall, 42.3% of MPN patients reported being unsatisfied with their current pain management plan. Despite this, only 43.5% of patients stated that their MPN providers discussed pain during office visits. Palliative Care (3.1%) and Pain Management (7.3%) were infrequently engaged. On the BQII, patients described being confident that cancer can cause pain (mean 4.2, SD 1.1) but did not necessarily expect to have pain following their MPN diagnosis (mean 2.2, SD 1.8). Conclusion Chronic pain (abdominal, bone) is a prevalent and undermanaged feature of MPN disorders. Chronic non-MPN pain is further complicated by the development of the disorder. Many MPN patients lack understanding on its prevalence and furthermore feel ill-equipped to manage it. Patients have, however, found symptomatic benefit from various pharmacological and non-pharmacological treatment modalities that require further exploration. Results from this study suggest MPN patients should be assessed regularly for pain and offered early referral to specialized services for evaluation, source identification and treatment. Table 1.

Abstract Introduction Patients with myeloproliferative neoplasms (MPN) typically experience debilitating symptom profiles and profound quality of life (QoL) decrements. Characterizing symptom burden in MPN clinical trials is vital to inform efficacy analyses. Previous studies have shown clinicians and researchers depend on patient-reported outcomes (PROs) to glean disease-related symptoms and signs of QoL decline. The current literature also shows that integrating PROs into the routine care of patients with cancer is associated with increased survival compared with usual care. However, the extent to which PROs are employed in MPN clinical trials is undescribed. ClincalTrials.gov is a registry of clinical trials mandated by the US Congress and implemented in 2000 by the National Institutes of Health. This study used data from ClinicalTrials.gov to evaluate the characteristics of MPN clinical trials over time and their use of PROs as primary and secondary outcomes. Methods The statistical software R and the rclinicaltrials package were used to download data from ClinicalTrials.gov. Trial data were included in this study if the following criteria were met: (1) the words essential thrombocythemia, polycythemia vera, myelofibrosis, or myeloproliferativeneoplasm (MPN) were used in the registered primary disease condition or official trial title; (2) the trial start date was between January 1, 2000 - July 1, 2018; (3) primary/secondary outcome data were available. Trial outcome data were then parsed for PRO text phrases including MPN-Symptom Assessment Form, quality of life, questionnaire, patient-reportedoutcome, and more specific PRO items (e.g., bone pain, concentration problems, and depression). Descriptive statistics and regression analysis were used to assess rates of primary/secondary outcomes over time. Results Clinical trial characteristics There were 535 trials satisfying the inclusion criteria. Since 2000, the number of registered MPN-related clinical trials ranged from 11 to 36 trials per year with 28 trials registered annually on average (Figure 1). Of the 535 trials, 470 (88%) were interventional and 65 (12%) observational. Trials often employed multiple intervention types including: drug (77%); procedure (28%); biological (19%); radiation (13%); genetic (3%); behavioral (2%); device (2%); dietary supplement (1%); other (24%) [percentages do not sum to 100% as categories are not mutually exclusive]. Eligibility criteria varied widely, though most used 18 years old as the minimum age requirement (71%; 379/535) and nearly all included both genders (>99%; 533/535). PRO outcomes over time Of the 535 MPN trials, the number of primary outcomes within MPN trials did not change over time (p=.50) with an average of 1.6 per trial. Around 8% of MPN clinical trials had PRO-related primary outcomes; this rate also did not change over time (Figure 1: solid red line; p=.97). However, the total number of secondary outcomes per trial has increased since 2000 (p<.001). From 2000-2005, 2006-2011, and 2012-2018 there was an average of 2.8, 3.3, and 5.2 secondary outcomes per trial, respectively. Also, the proportion of MPN clinical trials with PRO-related secondary outcomes has increased steadily over time (Figure 1: dashed blue line; p<.001). On average, from 2000-2005, 2006-2011, and 2012-2018 the proportion of MPN clinical trials with PRO-related secondary outcomes increased from 8% to 23%, to 33%. Conclusion Analysis of ClinicalTrials.gov data suggest that patient-reported outcomes are being implemented into MPN clinical trials at increasing rates. While this suggests that MPN trials are becoming more patient-centered, PROs are included more often as secondary endpoints than primary endpoints. This analysis also suggests an increase in the number of secondary endpoints in recent years in MPN clinical trials, consistent with observed trends of growing complexity and increasing amount of data captured in clinical trials in general.

Abstract Background: Polycythemia vera (PV), essential thrombocytosis (ET), and myelofibrosis (MF) are chronic myeloproliferative neoplasms (MPNs) characterized by clonal cell proliferation, splenomegaly, and significant symptom burden. Integrative medicine interventions may offer unique symptom management strategies. (Gowin, et al., EHA 2017). Here we describe integrative interventions utilized and association with symptom burden, quality of life, depression, and fatigue adjusted for lifestyle confounders. Methods:Patients were recruited via social media. Consent and online self-report surveys were completed capturing patient demographics, disease-specific data, integrative medicine utilization, symptom burden via MPN-Symptom Assessment Form Total Symptom Score (MPN-SAF TSS), depression screening via Patient Health Questionnaire (PHQ)-2, fatigue via Brief Fatigue Inventory (BFI), and overall quality of life (QoL). MPN-SAF TSS, QoL, BFI, and PHQ2 were compared by participation in the most frequently utilized interventions (Yes vs No). Intervention comparisons were adjusted for alcohol consumption, smoking status, BMI, current dietary modification, and MPN type using multiple linear and logistic regression. Results: Patients: A total of1087 patient surveys were consented. Of these, 858 had 10 or more responses. See Table 1 for patient characteristics. Integrative Medicine Therapies Descriptive Analysis: Integrative medicine therapies most frequently utilized by patients included aerobic activity (51.5%), massage (28.4%), yoga (25.6%), nutrition (25.2%), strength training (23.8%), acupuncture (19.3%), meditation (19%), breathing exercises (18.4%), chiropractic (16.2%), support groups (14.5%), mindfulness based stress reduction (13.6%), walking meditation (12.0%), pet therapy (9.4%), aromatherapy (8.6%), music therapy (8.0%), progressive muscle relaxation (7.0%), guided imagery (6.4%), homeopathy (6.3%), manual therapy (osteopathy/cranial sacral) (6.2%), reiki (5.8%), therapeutic touch (5.7%), Tai Chi (5.2%), art therapy (4.9%), traditional Chinese medicine (4.3%), Qigong (3.5%), cooking classes (3.0%), laughter therapy (2.9%), Ayurveda (2.4%), biofeedback (2.2%), dance therapy (2.1%), hypnosis (2.0%), resilience training (0.9%), IV vitamin therapy (0.8%), and narrative medicine (storytelling) (0.3%).Diet modification was reported in 47.7% of patients, including Mediterranean diet (19.0%), paleo/high protein/low carbohydrate (8.9%), vegetarian (8.6), plant based (5.2%), gluten free (5.2%), low FODMAP (1.8%), vegan (1.2%), and raw (0.6%) diets. Only 24% of patients reported receiving nutrition advice from their healthcare practitioner (HCP). Supplement utilization by MPN type was 162 patients (48.4%)in ET, 80 patients (42.8%) in MF, and 142 patients (45.2%) in PV. Overall, 20.6% patients reported not disclosing their natural product usage to their HCP. The most frequently utilized supplements included vitamin D, multivitamin, magnesium, omega 3, and calcium. Adjusted symptom association with integrative therapy intervention: MPN symptom burden: Aerobic activity (P=<.001)and strength training (P=.01) was associated with lower mean symptom burden. Use of massage (P=<001) and support groups (P=<.001) was associated with higher levels of symptom burden. QOL:Higher quality of life was reported in those receiving massage (P=.04)and support groups (P=.002). Lower quality of life was noted in those using aerobic activity (P=<.001)and strength training (P=.001). Depression (PHQ-2):Lower depression screening score was noted in those participating in aerobic activity (P=.006), yoga (P=.03), and strength training (P=.02). Fatigue (BFI):Lower fatigue was noted in those participating in aerobic activity (P=<.001) and strength training (P=.03). Higher fatigue was noted in those participating in massage (P=<.001) and breathing techniques (P=.02). See Table 2. Conclusion: In a geographically diverse MPN patient population, and when adjusting for healthy lifestyle practices overall, patterns of lower symptom burden, fatigue, depression, and higher QoL were revealed with integrative medicine utilization. Although limited by gender discrepancy and patient reported data, this study may offer a foundation to structure future integrative medicine trials to complement standard therapies in MPN patients.

Abstract Background: Smoking increases the risk of Philadelphia-chromosome negative myeloproliferative neoplasm (MPN) development as well as increases the risk of thrombotic complications, the major cause of mortality in this population (Blood 2017 130:4199). Guidelines suggest that management of more indolent forms of MPNs include the assessment and mitigation of cardiovascular risk, which includes the management of smoking-related risks (NCCN Guidelines. 2017). In this analysis we sought to examine smoking outcomes and opinions from the perspective of the MPN patient, with the goal of helping to guide MPN patient care. Methods: The internet-based survey was developed by a team of MPN investigators and administered via Mayo Clinic's REDCap. Online recruitment was facilitated via multiple MPN-related webpages including the MPN Forum, MPN Net, MPN Research Foundation, and MPN Voice during June of 2018. Surveyed data included disease demographics such as thrombosis, medications, and smoking history. MPN-specific symptoms were assessed utilizing the MPN-10 (Blood. 2011 Jul 14;118(2):401-8). Data: Participant Demographics: Of the 607 patients who clicked the survey link, 435 patients were eligible for the survey and completed the questions regarding smoking history. Of these, 254 (58%) reported no history of tobacco use, 161 (37%) reported being ex-tobacco users, and 20 (5%) reported being current users. Among those who reported current tobacco use, 50% used premade cigarettes, 27% used self-rolled cigarettes, 20% reported vaping, and 3% reported chewing tobacco or snuff use. Respondents were most often from the US (67%), Australia (12%), the UK (6%) or Canada (6%). The distribution of respondents included 28% with myelofibrosis, 44% with polycythemia vera and 27% with essential thrombocythemia. Over one quarter (26%) of patients had experienced a prior thrombosis, with the most frequent thrombosis types being DVT (9%), stroke or transient ischemic attack (8%), abdominal vein thrombosis (5%), myocardial infarction (2%) and cerebral vein thrombosis (2%). When comparing current/former smokers to never smokers, no significant difference in thrombotic frequency was observed. Smoking Correlates: When evaluating MPN symptoms, current/former smokers reported higher severity of fatigue (mean 5.6 vs 5.0, p=0.02) and inactivity (mean 4.0 vs 3.1, p=0.03) compared to nonsmokers. Additionally, current/former smokers were more likely to experience early satiety (69% vs 58%, p=0.03), inactivity (80% vs 71%, p=0.04), concentration difficulties (82% vs 73%, p=0.04), and reduced quality of life (mean 6.1 vs 6.5, p=0.03) compared to nonsmokers. Although not significant, a trend of higher symptomatology was observed for former/current smokers compared to nonsmokers (MPN-10 total symptom score [TSS] mean 30.4 vs 27.0, p=0.07). Former/current smokers were also more likely than nonsmokers to report heavy alcohol consumption (>7 drinks per week in 9.6% vs 4.0%, p=0.03) and using opioids for pain management (24% vs 11%, p=0.001). Smoking Opinions and Care: As shown in Table 1, less than half of current/former smokers (43%) reported having their physician discuss tobacco use with them. Less than 40% of MPN current or previous smokers were aware of the risk of MPN development due to smoking, although the majority (83%) were aware of the increased thrombotic risk. Less than one quarter (43/181) of current/former smokers reported having utilized pharmacologic therapy to aid cessation. Conclusions MPN patients with current or previous tobacco use demonstrate significantly higher symptom burden than non-smoking counterparts. In terms of patient care, less than half of patients who are current or previous smokers recall having a physician discuss their smoking habits with them. These results highlight the need for enhanced MPN patient counseling by health care providers, both regarding the risks of smoking and available methods to aid cessation.
